Overview

The MCF51AC family, comprised of pin-compatible 8-bit and 32-bit device duos, is the third family in the Flexis® series. The Flexis series of controllers is the connection point on the NXP® Controller Continuum, where 8- and 32-bit compatibility becomes reality.

The MCF51AC256/128 device extends the low end of the 32-bit ColdFire® controller family with up to 256 KB flash memory, a controller area network (CAN) module, a 16-bit FlexTimer module, 24-channel, 12-bit analog-to-digital converter (ADC) and delivers up to 25 MHz in bus frequency. The 32-bit MCF51AC256/128 is pin-, peripheral- and tool-compatible with the 8-bit S08AC128/96/60/48/32 devices. They share a common set of peripherals and development tools to deliver the ultimate in migration flexibility.

1 .- The members of MCF51AC128 with CAN support have 32 KB RAM. The other members have 16 KB RAM and not all members of the family support CAN

The EMC performance of an application using this microcontroller is dependent on a number of factors that are outside the control of NXP Semiconductor. These factors include but are not limited to industrial design, mechanical design, printed circuit board design and layout, components, connectors, and cables. NXP Semiconductor is unable to guarantee the EMC performance of any microcontroller in a specific application. Careful consideration must be made when designing any application to ensure the necessary level of EMC. For more information on designing robust EMC systems please refer to application note AN2764.
